#4

Older version of the hive doesn’t support primary key but this support has been added in 2.1.0 version of hive. So please upgrade the hive version to 2.1 or above if any.

Hi @Janagaraj_Appusamy,

We will need to upgrade the entire cluster for the same. We will add this in our pipeline.

Thanks,

Hi Abhinav,

When can we expect latest version of hive?
The current version available is 1.2 that is deprecated.
As you said that you need to upgrade the entire cluster so i guess the versions of all other techs will also be deprecated versions in cloudxlab.

Thanks and Regards,
